ROLLER COTTON-GIN.

SPECIFICATION forming part of Letters 'Patent No. 435,886, dated September 2, 1890. Application tiled April 28, 1890.. Serial No. 349,783. (No model.)

To @ZZ wiz/m t may concern:

Be it known that I, FRANK l1. CHASE, of Haverhill, in the county of Essex and State of Massachusetts, have invented a new and use- 5 t'ul Improvement in Roller Cotton-Gills, of

which the following is a specification.

My invention relates to that class of cottongins known as roller-gins, and it consists in the application thereto of a Wwliippeig the lo use and construction of which are fully described below and illustrated in the accompanying drawings, in whichd Figure l is a central vert-ical section of the operative parts of a roller cotton-gin with my I invention embodied. Fig. 2 is a side elevation in detail of a portion of the gin. Fig. 3 is a perspective view showing portions of the drawing-roller and the whipper in position.

Similar letters of reference indicate like zo parts.

A represents the frame.

I3 is the table from which the seed-cotton is fed into the machine.

C is the drawing-roller.

D is the beater yor stripper driven by the wheel D'.

E is the upper dollfer for throwing back the unginned cotton.

F is the lower dotler for taking down the 3o ginned cotton to the board ll, and I is the pressure-bar adjusted by the screw mechanism J, none ot' said parts being new in this invention, and the operation of them being well known in the art to which this device appertains.

J .l' are lingers and a linger-imi1 constructed as described in Letters Patent numbered 418,908, dated .Iailuary 7, i890.

On the shaft C of the drawing-roller C is ixed a crank K,to which is pivotally secured a rod or pitman L,'\vbose opposite end is pivotally secured to the crank N, whose hub N is rigidly secured on the oscillating shaft O, having bearings in the journal-box O. From this shaft O extends a series of rods P, preferably metallic, the whole constituting what I terni a whippeiz R is a horizontal bar, preferablyv of angle shape, as shown, bolted to the table B. Bars or wires S extend from the bar R to a similar 5o bar R', parallel with the bar R and lying next and on the fingers J, the whole forming a grate. The rods P lie, as shown in Fig. 3, between the stationary bars or wires S. It will readily be seen that the rot-ation of the rollershaft C causes the shattor whipper-fraine O to oseillate and the rods P to swing back and forth rapidly between the bars S ot' the grate. As the cotton is dropped onto the grate, therefore, the whipper, striking it, bats the seeds 6o outthat have already been. stripped of their lint. In other words, it removes the seeds that have been stripped of their lint, having been ginned and thrown back by the beater.

Having thus fully described my invent-ion, what I claim, and desire to secure by Letters Patent, is-

l. In a roller eotton-gin, the combination of the oscillating shaft O and rods P, constituting the whipper, and traine, as R R', and 7o the bars constituting the grate, constructed to operate substantially as set forth.

2. In combination, the roller C and rollershaft C', crank K, pitman Ii, crank N, oseillating shaft O, provided with the rods P,and stationary frame R R and bars S, all eonstrncted and arranged substantially as described.
